OIL-CAN.

SPECIFICATION forming part of Letters Patent No. 556,741, dated March 24, 1896. Application led January 16,1895. Serial No. 535,131. (No modeln To 60N, whoml it may concern:

Be it known that I, WARREN A. DURR1N,a citizen of the United States, residing at XVoodville, in the county of St. Croix and State of lVisconsin, have invented a new and useful OYLCa-n, of which the following is a specification.

My invention relates to an oil-can designed for household use; and the objects in view are to provide a simple and efficient device adapted to be used in filling lamps and similar articles without the necessity of inclining or tipping the can; and, furthermore, to provide means whereby the ilow of oil from the can may be regulated. with greater accuracy to prevent overflow and similar disadvantages of the ordinary form of can.

Further objects and advantages of thisinvent-ion will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

1n the drawing the figure illustrates a central lvertical section of a can constructed in accordance with my invention.

1 designates the can, which may be of cylindrical or other form in cross-section and which is provided with concaved upper and lower heads 2 and 3 to resist internal pressure, and arranged in the can is a cylinder 4, having at its lower end au opening 5 which communicates by means of an air-inlet tube G with an opening 7, which is :formed in the upper head of the can. This opening 7' is covered by a reticulated cap 8 to prevent the admission of dust or other foreign matter. The opening 5 at the lower end of the cylinder is provided with a valve 9, which opens inwardly or toward the cylinder to allow the admission of air to the latter and prevent the exhaust thereof at this point. Operating in the cylinder is a plunger 10, provided with suitable packing 11 and having a rod 12, which passes through a guide-opening 13 in a removable perforated cap la, which is threaded upon the upper exterior terminal of the cylinder. Said plungerond terminates outside of the can in aknob or handle 15. Communicating with said cylindernearits bottom is an air-supply tube or conveyer 1G, which terminates in an air-chamber 17 at the top of the can, the opening by which said pipe communicates with the chamber being closed by a valve 18, which opens upwardly to allow air to escape from the supply-tube 1G into the airchamber. Said chamber communicates with the interior of the oil-can by means of a port 19, and the chamber is provided with a removable cap 20, by which access is given to the interior of the chamber for the purpose of cleaning the same and repairing the valve 1S. It will be seen also that the perforated cap 14 at the upper end of the cylinder is removable for the purpose of withdrawing the plunger and thus gaining access to the valve il.

Located in the oil-can, preferably near one side and parallel with the axis thereof, is an extension oil-outlet pipe 21, consisting of telescoping inner and outer sections, 22 and 23, of which the former terminates at its upper end in a spout 24 and the latter is secured permanently in the can, A stuffing-box 25 is located at the upper end of the fixed or exterior member, 23, of the extension outlet-pipe to prevent leakage around the inner member, 22, and at the same time provide for the longitudinal and rotary adj ustm ent of said member 22, whereby the spoutmay be arranged in the most desirable position for discharging the contents of the can. The lower end of the station ary member of the outlet-pipe is closed by an inwardly-opening valve 2G, to which is pv'otally connected t-he lower end of an operating-rod 27, and said operating-rod extends through a guide 2S in the top of the can and is provided with an actuating-spring 29, by which said valve 26 is normally held closed. The operating-rod terminates at its upperend in a knob 30, which may be pressed to communicate motion to the valve 2G, whereby oil is admitted to the outlet-pipe.

The outlet-pipe and operating-rod are connected to and supported by a removable cap 3l, threaded upon aflange which surrounds the opening 33 in the top of the can, whereby said parts may be detached from the can to provide for cleaning and repairing the same. The supply-opening 3i, which is formed in the top of the can, is provided with a removable cap 35.

This being the construction of the improved oil-can, it will be seen that oil is introduced through the capped opening 34, and when it is desired to discharge oil from the can the ICO The pressure of air in the oil-can then forces the oil through the extension outlet-pipe, and when the desired quantity hasbeen discharged the release of said operating-rod will be aeeomi panied by the closing of the valve, thus immediately cutting oii' the discharge of oil..

In this Way all of the oil in the can may be withdrawn7 and as long as the air which is contained in the can above the oil remains in a state of compression no further ope-ration of the pump is necessary.

It will be seen that back flow or escape of either oil or air is prevented by the arrange nient of th'e valves 9 and 18, and in ease oil is spilled upon the concave top of the cany said can may be inclined to cause the oil to How through the reticulated cap 8 inte the;y

inlet-pipe (i, whereupon the operation of ythe plunger will discharge the oil into the inte rior of the can.

It Will be understood that in practice various changes in the form, proportion, and they minor details of construction may be resorted to Without departing from the spirit or saeriiieing any of the advantages of this invention. llaving described my invention., I claim-1 l. The combination with an oil-can having an outlet-pipe, of force-feed mechanism having a cylinder arranged within the can, a plunger operating in said cylinder and provided with a rod which projects to the eXte-v rior of the can, an inlet-pipe communicating with the inner end of the cylinder and provided 'at its outer end with a retieulated cap, an inwardly-opening valve for controlling the passage between the inlet-pipe and the eyiind'er, and a valved supply-pipe eommunif an outlet-pipe7 of a cylinder arranged vertically in the can and provided at its upper end with la removable perforated cap, a plunger operating in said cylinder and provided with a rod extending beyond said perforated cap` 'an inlet-pipe communicating with the lower.` end of the cylinder and provided at its outer end with a reticulated cap, a valve controiling the communicating passage between the inlet-pipe and the cylinder and arranged in the latter whereby it is accessible when the plunger is removed, an air-chamber i7 having a removable 'cap7 and a supplyppe vcommunicating at one end with the cylinder and at the other end by a valved passage with said air-chamber, the valve being arranged in the chamber and being accessible when the cap thereof is removed, said ainehamber being` in communication with the interior of the oil-can, substantially as speciiied.

The combination of an oil-can provided with upper and lower concaved heads, an oil-outlet spout, and force-feed mechanism having a pump provided with an inlet-pipe which terminates in a retieulated cap contiguous to the upper head of the can, and a supply-.pipe which vis in communication with the interior of the can, said inlet and supply pipes being provided with controlliiig-valvesq substantially als speeiiied.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses. y
